There are various methods for entering the BIOS or CMOS setup depending on the make, model and age of your computer. I will try and explain some of the most popular methods.

Most modern computers will require you to press one of the following keys during start up:

  • F1
  • F2
  • DEL
  • ESC
  • F10

You should press the key when you see a message such as press <f2> to enter BIOS or try tapping the appropriate key slowly during startup.

On some modern computers, pressing and holding down a key during boot will cause a stuck key error. This may give you the option to enter BIOS setup

Older computers may require one of the following key sequences during startup:

  • CTRL + ALT + ESC
  • CTRL + ALT + INS
  • CTRL + ALT + ENTER
  • CTRL + ALT + S
  • PAGE UP KEY
  • PAGE DOWN KEY

If the above suggestions do not work please check the access key lists below.
